CAR-PUSHIER.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed June 14. 1907- Serial No. 379.072.

To all whom 'it may concern:

Be it known that I, ALEXANDER E. BROWN, a citizeri of the Unted States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a new and useful Improvement in Car-Pushers, of which I herebydeclare the following to be a full, clear, and exact description, duereference being had and intended to the several drawings. accompanyingand making a part of this specification.

My invention is intended more particularly, for use for the purpose ofbringing cars up and into the so-callcd car-tipples to be therebydivested of their load, and, by an arrangement thatunlike prevailingmethods of feeding cars into tipplesis not confined to a single fixedlocation, in the vicinity of a stationary tipplc, but that may travel toany desired distance, on surface tracks like anordinary locomotive,thereby not only enabling it to serve more than one car, in a singlemovement, but also rendering it possible to have the tipple itselfportable along the dock, or unloading ground.

As is well llIlClClctOOd by those who have to do with the handling ofcoal, ore or other gross material by modern methods, one or another ofthe special forms of tipples in use, are stationed at some predeterminedpoint where the loads are to be discharged. An approach trackleads tothe tipple on an ascending grade above a sunken subsidiary track ofsimilar grade, and the cars are sent in on to this approach track fromthe main lines in the yard by connecting swtches. track is a frame-workcar, commonly known as the ground-hog, that can be drawn up thedeclivity on its track toward the tipple by a drum and cable apparatusin or nair the same. Both this and the approach track have substantiallythe same grade-angle, so that a loaded car, when switched upon thelatter track, will take its place, by force of gravity, at the outerterof this track and immediately in front of and against the ground-hogwhen the latter is in a corresponding position on its own track. If theground-hog is now pulled in towards the tipple it will of course propelthecdr up the declivity until it entersthe tipple and is in place forclamping and overturning.

It is manifest that unless provision is made for the purpose by anundesirable and often impracticable extension of the sunken-track, and,at an excessive increase of the drumiaiad cable mechanism, thisarrangement will not b'eade'q-uate for handling more than one loadedcarat a time, and, further, that, however the dimensions, locationandeapacity of a feeding apparatus of this kind, are. originally laidout,-neither these nor the of the tipple itself can in any manner be .Wlchanged tom'eet varying conditions as they arise On the sunken- I said,,my present invention isfintended,

among other things, to dispense with the need of a sunken track and theconsequent limited range of the pusher and to do away with any fixedness of the lipple itself, at the same time, enabling them both Lobefreely traversed from one point to another, as occasion requires, andwithout need of new or special preparation therefor.

As will appear my invention is further extended to and covers a specialform of pusher herein described, more especially for use in connectionwith hoisting and conveying machines of a certain type as pointed out.

In the drawings Figure 1 is a side elevation of a tipple and train ofcars in position to be administered to by the pusher shown, Fig. 2 is aplan view of the same. Fig. 3 is an enlarged side-elevation of a car andpusher when brought up thereby immediately before the tipple. Fig. 4 isa plan View of the same. Fig. 5 is an enlarged view of the relativeposition of the pusher when the car is thereby brought within the tipplein its position for overturning. Fig. 6 is an enlarged side view of thepusher as a whole. Fig; 7 is a plan view of the same. Fig. 8 is an endview of the same. Fig. 9 is a sectional plan view, in the direction ofthe arrows, through a; a; in Fig. 6. Fig. 10 is a side-elevation ofdetails shown in Fig. 9. Fig. 11 is an end elevation of said details.Fig. 12 is a vertical section of the lower portion of the front arms ofthe pusher. Fig. 13 is a horizontal sectional view, in the direction ofthe arrows, on the lines y, y, of Fig. 12. Fig. 14 is a side elevationof a special form of pusher for switching purposes, more particularlyfor usein connection with a style of hoisting and conveying machineknown as a fast plant. Fig. 15 is a plan view of the same.

'Fig. 16 is a horizontal sectional plan view on the lines 2, z, of Fig.14. Fig. 17 is an end view of said special form when in engagement withcars (shown in dotted lines) at each side of the same, and, Fig. 18 is avertical sectional view. on the lines to. w, of Fig. 14.

Similar reference characters are used on similar parts throughout thedrawings.

Insaid drawings A, A are parallelstruts connected to posts P, whichlatter, in turn, are connected together by cross-girders G G into arectangular mme-.

work top supported by said posts. The latter are themselves'supported onsills S S. each made up in this case of a pair of wheels W and Wcarrying the entire framework. Suitable motors M M, through a train ofgearing indicated by O and O and shafts R and R drive said trucks. Forthe purpose of traction, a pile of ballast, of concrete, or othermaterial (the upper surface .of which is indicated by the line B and thelower by B) may be added.

The form of pusher for tipples, shown in Figs. 1 to 14 is characterizedby having the two arms D and D,

Trucks T T, are.

Y swivel with respect to said trucks.

extending horizontally along the top of said framework so as to overhangor project beyond the same to a distance substantially the same as thatbetween the exterior of the tipple and the car when the latter is placedfor overturning within the same, and thereby, permitting the car to bepushed to said place without the pusher itself coming in contact withthe tipple. Said arms are pivoted to the cross-girder G, at the points 9I and g, to enable them to be moved laterally or distended about saidpivotal points, and thrown out of engagement with the car when desired,and to either side respectively, of the cars trackw-ay. Good construction requires that said pivotal points should be located at suchpoints on the cross-girder G that, when in the engagement referred tothat they will be in direct overhead alinement with the car to bepushed.

The forward ends of the arms I), D, are carried down-- wardly at rightangles by the rigid parts or portions E E, to a distance, that willbring their lower: ends substantially on a level with the bumpers of thecar to be moved, when the pusher and car are on the same track, Theparts E, E are each made up of two oppositely faced channels that areheld, in such relation, by cross-plates p p that reach downwardly ontheirexterior to a point somewhat above their lower ends The parts E E,throughout the portion carrying said cover-plates. will thus have abox-section. In order to afford a level trackway for the track wheels K,K, through the interior of the parts E E, below said coverplates, theinner opposite faces of said channels are reinforced by the flat-facedtrack-bases t, that are fitted in and along such interior portion,against the beveled surfaces of the channel flanges. Arranged asfourwheeled trucks to bear and travel upon said track-base are thewheels K K which, as will be seen, are, in each case connected togetherby a housing H. H. To provide or make up for any relative inequality, ina particular case, between the two points 011 the surface of a car, atwhich the parts EiE engage the same, said housings H and H are given adegree of compensating As shown in the drawings, this is effected byusing the transverse journals, or cylindrical bearings, b b for thetruckwheel axles a a and connecting the same to and within the housingby the opposite, integral trunnions u, u on said bearings. Forconvenience said housing is shown as composed of the separablehalf-pieces h and h that are bolted together. as indicated, when thetrucks and journals are in their places therein. The housing should beof suitable dimensions to project both before and behind the oppositechannels between which it is to vertically oscillate. I

To prevent its falling below the bumpers in case of a sudden orunexpected disengagement therefrom it is well to provide the housings attheir top with the projecting flanges f and f. The trucks, thus made up,are inserted within and between said opposite channels, at thelower endsof the parts E and E, with the wheels K, K, against the track-plates t,and are secured, in place, by bolting across the lower ends of saidchannels, as shown (Fig. 12), the U-shaped bars t, t. Figs. 12 and 13,show a rubber bumper m bolted to the upper face of said bars, to meetsaid trucks when at the lower limit of their travel.

In the drawings, L is the tipple proper (Figs. 2 and 4) which is shownas portable, being mounted on trucks that travel on the rails O CL Therails upon which the pusher travels in the performance of its prescribedfunctions, in the type shown in Figs. 1 to 14, are denoted by O and Cwhich are respectively located on the outer side of the rails C C of theapproach track to the tipple for loaded cars. 7

A feed-rail, for a supposed 3d-rail electrical system, havingcontact-shoes d d, is indicated by C in the drawings.

h, h are couplers provided at the front end of the pusher, to engagecorresponding couplers in the tipple when it is desired to pull thelatter, by means of the pusher, along its rails from one operative placeto another.

In order to actuate and control the arms D D, laterally about theirpivot, and thereby engage and disengage the same from a car, and also togive clearance to the frame-work of the pusher when it is desired to runthe same over a given car, to engage a car for instance, at the front orrear of the same, suitable means, as by the rope and sheave systemindicated in dotted lines in Fig. 8 should be provided.

In order to enable a pusher to be used for bringing one or more cars toa particular place, as beneath the overhead tramway of the so-calledfast plants of the hoisting class of machines, I have devised, andspecilically claim herein, a specially arranged locomotive, preferablyelectric, which is illustrated in Figs. 14 to 18 inclusive; As willappear it is intended to travel on its own track e e, which, unlike theform first described, lies entirely on one side of the track on whichthe car to be propelled travels and is substantially parallel therewith.The form shown in the drawings sets out a locomotive of this sort whenoperated between two parallel car tracks, and, under such conditionsengaging and being able to push cars on either track, or on both at thesame time. The method of propulsion thus shown also differs essentiallyfrom the first in omitting the forward arms D D, and, employing fortheir functions, the arms F F that are pivoted vertically and aredistensible laterally about their pivots, from the sills of thepusher-car, preferably near their central part. These arms, as shown,are attached to the sills and are afforded their pivotal movement bymeans of trunnions k k which have their bearing on said sills. v

As will be manifest the last described method of bringing up cars bysaid pusher, requires a special track for the same to be prepared alongand parallel with those on which the cars themselves move and leading tothe delivery point for the loads. If deemed necessary a second parallelcar track may be provided immediately on the other side of thepusher-track, and, like the other, within range of the lateral arms Fand F. These tracks-may of course, be either the main. railroad tracks,or the yard-tracks on which cars are switched from the main tracks. t

The pusher-locomotive can now be brought to the. side of a given car, ortrain of cars, and the arms F or F, or both, as the case may be, thrustout behind such .1

car, or any car in a train, and, in position to engage the sive therails of the track on which the pusher moves straddle the approach trackto the tipple, and the frame-work above the truck is carried up abovethe height of cars, with a clear open space beneath the same. Thisconstruction, when the arms D D are distended outwardly, permits thepusher to pass over any car or cars and, if desired, engage, forinstance, one or more, of the forward cars of e'rf train, or, passbackwardly, over a train to engage cars at or toward the rear thereof,should it be desired to push the entire train, or more than one memberof the same toward the tipple at one movement. In, this case, as hasbeen before observed, the tipple may be made portable and the pusherused to also couple to and pull or push the same from one station toanother in the unloading district.

Having thus described my said invention, what I wish to secure byLetters Patent is 1. A locomotive for pushing cars or suitabledimensions to span the trackway of said cars, and provided withforwardly distensible arms for engaging the same for the purpose,substantially as shown and described.

2. A locomotive for pushing cars, along a. track adjoin ing the track onwhich it is to move/and provided with laterally distensible arm or armsfor the purpose, substantially as shown and described.

3QA car-pusher made up of the combination of trucks, or track-wheelstherefor, an overhead frame-work or structure mounted on and carried bysaid trucks or wheels, of suitable dimensions to span the carswhenbrought above the same, distensible arms on said frame-work forengaging the cars, and suitable means for driving said trucks, orwheels, all substantially as shown and described.
